nAN'rERitl I shines-enemas macaw, 152s sai'a m seaeei To' alfwhom amayeamem- V Beit known that I; J .J Ensure, a citizen-of the uniteestates of America, re siding at North Plainfiel'd', in the county? of Somerset and Statefof New Jersey,ghave'invented certain new and] useful Improve-'- men'tsin Lanterns; and I do-h'ereby declare thatthe following isa full, clear, concise, and exactdescription of the invention, such as will enable others skilledin the art to which it appe'itiiin's to" make and use the same. I t Y 1 p This invention relates to" improvementsin lanterns, havingfor aiiobj ect"to provide-a lantern especially adwantageous for, use upon. bicycles and similar vehicles, haying a plurality of reflectorsinth'e same arranged to emit light rays from the front, rear and one side wall of the lantern housing, thereby affording visual warning to approaching vehicles to readily locate thebicycles so equipped and accordingly avoid the same.

It is likewise an object of the invention to provide a lantern with a novel form of main reflector positioned in the lantern housing in a manner to reflect light rays emitted from the light source and to direct the same through the various lenses of the lantern in amost effectual manner.

Other objects will be in part obvious and in part pointed out hereinafter.

In order that the invention and its mode of operation may be readily understood by persons skilled in the art, I have in the accompanying illustrative drawings and in the detailed following description based thereon, set out one possible embodiment of the same. I

In these drawings:

I Figure 1 is a horizontal section through a lamp constructed in accordance with the invention;

Figure 2 is a fragmentary vertical section therethrough taken on the line 22 of Figure 1, looking in the direction in which the arrows point; I

Figure 3 is a detail in elevation of the main reflector;

Figure 4 is an elevation of one of the secondary reflectors;

Figure 5 is a reduced side elevation of a modified form of the main reflector; and

Figure 6 is a frontelevation of the same.

Having more particular reference to the drawings, in connection with which like characters of reference will designate corresponding parts tiireu iieua uie ifltenuet may bestatedto comprehend a antern Ho regenerate-day the es-a circul' 'r in"crosssfection a I fin Fig! ure 1 and aain 'windews thefrbnrauu side-walls thereof p'rovidedI with were spondingly formed frames 2 adapts-a tere?- ceive lenses 4, and therein, s'1ic lenses being of 'different colors, as for example, the front lens being white,- the lens 45* being green and the lens" 5' red. -A"sui tahle liglit source, such as a liquiclfifliel burner; 0' an electrical incandescent lamp 'fi' is air ged concentrically of the housing 1, a s' s'how n' the Figure 2, being adapted to havejtli'e light raysTemitted therefrom directed thmug-H the lenses 3, 45 and 5; bran olivine-s purpose.

With a View towards providing means for the reflecting of light rays to the lenses 3, 4L and 5, I provide a main reflector indicated by the numeral 7, consisting of a metal body formed with a highly polished outer surface and having the lower portion thereof arranged with diagonally disposed or substantially V-shaped reflecting surfaces, while the upper portion thereof is concaved as at '8 and provides means for reflecting certain of the light vrays emitted from the light source 6 forwardly through the front lens 3. This main reflector 7 is preferably secured in position by .means of a metalstrap 9 passing aboutitsintermediate por tion and having the opposite extremities thereof passed through openings in the rearward portion of the lamp housing 1, whereby they may be engaged with an object, such as indicated at 10, to which it is desired tosecure the lamp, the outer ends of such strap being bent at right angles as indicated at 11 or otherwise formed topermit of such connection.

Secondary reflectors formed of sheet meta and having the outer surfaces thereof suitably polished are arranged within the housing 1 and as will be noted, are of substantially V-shaped formation in cross section, the marginal portions thereof being flanged as indicated at 13 whereby they may be secured to adjacent portions of said housing 1 as by soldering or similar fastening means, such secondary reflectors being preferably positioned at points in proximity to the opposite sides of the front window of the lamp housing 1 or the lens 3.

Because of the relative positioning of the main reflector 7 and the secondary reflectors 12 within the lamp housing 1, it will be understood that certain of the light rays emitted from said lamp will be reflected upon the V-shaped or diagonal lower portion of the main reflector and thus reflected outwardly through the lenses 4 and. 5 arranged in the side walls of the housing. Others of the light rays will be reflected from the concaved upper portion 8 of the main reflector and directed forwardly through the lens 3.. Those light rays projected in a forward direction from the light source 6 will engage with the bevelled sides of the V-shaped secondary reflectors 12- and in consequence, will be reflected therefrom through the front and side lenses 3, 4; and 5. In this way, it will be appreciated that maximum illumination will be provided by the lamp through its light source 6 and in consequence, that the colored lenses 3, 4 and 5 will be rendered readily visible in darkness, enabling persons to readily locate the able for use upon bicycles, since, the forward 1 white lens 3 will permit of the illumination of the path being traversed by the vehicle, while the colored side lenses formed by it will offer ample warning or signals to vehicular traflic and pedestrians.

I claim:

In a lantern comprising a housinghavin windows in the front and side walls thereof, lenses positioned in each of said Windows, a main reflector immovably positioned within the housing adjacent its rearwall intermediately of said side windows and in direct alignment with the front window, said reflector comprising a body substantially V- shaped in cross section in its lower portion and having one face of the upper portion thereof vertically curved and extending throughout its width at substantially right angles to the V-shaped lower portion of the same, and secondary reflectors fixedly secured within the housing at points in proximity to the opposite sides of the lenses in the front wall thereof. I

In witness whereof I have hereunto set my hand.

CHARLES J. JENSEN.
